As revealed by Autosport earlier this week, the FIA has issued a draft technical directive stating that from the Singapore Grand Prix it is to take a tougher stance on the flexibility of bodywork – especially front and rear wings.
The FIA stated in the document that it believes outfits are exploiting "regions of purposely design localised compliance" plus "relative motion between adjacent components" to deliver a significant boost to aerodynamic performance.
It added that it felt designs that rotated around fixing points or flexed in certain specific areas were in breach of the regulations.
While the TD is understood to not just be aimed at one team, with several squads having been under the spotlight, it is clear that suspicions have swirled for several months.
Speaking at the Italian Grand Prix, leading team bosses welcomed the FIA intervention, as they suggested that the governing body would only have taken action if it felt some squads were pushing the rule boundaries too much.
Red Bull F1 boss Christian Horner said: "It's not something that affects us, but we've seen a few rubbery nose boxes, shall we say? So, we'll see those get addressed, I guess, in Singapore."
